Building a Fortnite Backend

Backend Fundamentals

When building a backend for your application, one of the first and most important decisions you'll need to make is choosing a programming language and runtime environment. This choice will impact everything from development speed to performance, scalability, and the ecosystem of tools and libraries available to you.

🎯 Choosing a Programming Language

There are many excellent options for backend development, each with their own strengths:


🚀 Our Focus: TypeScript with Cloudflare Workers + Hono

For this documentation, we'll focus on TypeScript running on Cloudflare Workers with the Hono framework. This combination offers several compelling advantages:

⚡ Why Hono instead of Express?

  • 🏎️ Fast & Lightweight - Optimized for edge environments with minimal overhead
  • 🔄 Express-like API - Familiar patterns if you've used Express.js
  • 📘 TypeScript-First - Built with TypeScript from the ground up
  • 🌐 Web Standards - Uses standard Web APIs for maximum compatibility
  • 🔧 Middleware Ecosystem - Rich set of middleware for common functionality

📚 What You'll Learn

In the following sections, we'll cover:

🎮 Fortnite-Specific Implementation

Then, we will get started by implementing some basic Fortnite API endpoints, which will continually get more complex as we go:

  • Player Authentication - Login/logout systems
  • Item Shop - Daily rotating cosmetics and items
  • Battle Royale Matchmaking - Player lobbies and game sessions
  • Player Stats & Progression - XP, levels, and achievements
  • Friends & Social Features - Friend lists and party systems

✅ Prerequisites

Before diving in, you should have:

  • 📘 Basic knowledge of JavaScript/TypeScript
  • 🌐 Familiarity with HTTP concepts (requests, responses, status codes)
  • Understanding of async/await patterns
  • ☁️ A Cloudflare account (free tier available)
